During this process, the surgeon removes the epithelium (the extremely thin outer layer) of the cornea using an alcohol solution, a buffing device or a blunt surgical instrument (as compared to creating a thicker corneal flap as in LASIK.) Subsequently, the underlying corneal stroma is then reshaped with an excimer laser (same as it is during LASIK). After the laser treatment is finished, a bandage contact lens inserted to protect and secure the epithelium in place as it heals. A new epithelial layer usually grows back within five days.
The optimal treatment will depend on the characteristics of each patient’s eyes & this will be determined during the pre-LASIK assessment.
At Lee Hung Ming Eye Centre, we offer both IntraLase Bladeless LASIK and Advanced Surface Ablation.
